A well known radio, in the same style as the Cobra 148.  As standard this radio operates on the European (Mid) band only, on AM, FM, USB, LSB.

Multimode export versions are also available with 240 channels and operating on FM, AM and SSB.  Please check the legal requirements for your country before ordering the export model. It can be supplied as an export radio for no extra charge.

If you want a "traditional" style SSB radio rather than one of the various current "PC programmable" radios then this could be for you, standard channel change and traditional clarifier.

Optional extras available include a plug-in frequency counter.

Note: this radio does not have the standard UK FM channels on it.
